To a/ZZ whom t may con/cern:

Be it known that I, OSWALD S. 'MEARS, a citizen of the United States,residingat Bloomtown, in the county of Accomac and Stateof Virginia,have invented Va new and` useful Ship-Rudder, of which the following isa speciication.

This invention relates generally to shiprudders, and more particularlytoa supplexo mental or emergency rudder which is normally contained withinthe ship or vessel and is not brought into action or operation unlessthe main rudder is carried away orbecomes unmanageable. As a generalrule a ship is vided with one rudder, and when this rudder is carriedaway by the heavy sea and by striking an obstruction the ship isunmanageable until another rudder can be rigged and brought intooperation, I am also zo aware that a supplemental rudderhas beenYarranged adjacent to a main rudder and held inoperative so long as themain rudder is in position. This supplemental rudder, however, is liableto be carried away the same as the main one.

The object of my invention, therefore, is to provide a supplemental oremergency rudder which is normally contained within a vessel and istherefore not exposed the same as the main rudder, said supplementalrudder. being capable of being moved into or out of. operation, asdesired, and by mechanism contained within the vessel.

With these objects in view the inventionY consists, essentially, inproviding a longitudinal chamber adjacent to the stern-post of a vessel,said chamber having side openings adjacent to the said stern-post, and arudder movable within the said chamber and adapted to be movedrearwardly into the open space, and means for supporting and moving thesaid rudder.

The invention consists also in certain de tails of construction andnovelties of combination, all of which will be fully describedhereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a viewshowing the stern end of a vessel, the supplemental rudder being movedinto operative position for the pur- Serin no. 104,513. un man.)

pose of more clearly illustrating its location and operation. Fig. 2 isa sectional view of the ship,-the supplemental rudder being arrangedWithin the vessel, said view also illustrating in elevation themechanism for moving the said supplemental rudder in an operativeposition; and Fig. 3 is a sectional view taken on the line 3 3-of Fig.V2.

Referring to the drawings, A indicates the hull of the vessel, B thestern-post, B' the 6o keel, C the main rudder, and D the rudderpost, allof which are of the-usual construction.

The ship is provided with a longitudinal chamber E in aiinement with thestern-post B and adjacent thereto, said chamber having side openings Eadjacent to the juncture of the stern-post and keel, as most clearlyshown in Figs. 1 and 2. The supplemental or emergency rudder F isnormally contained within 7o the chamber E and in advance of the sideopenings E', said rudder being pivotally connected to a movablestern-post G and provided with a rudder-post II. Movable sternpost G issupported at its upper end by means of 'a suitable carriage G', whichtravels upon a track G2, and at its lower end is arranged abearing-roller G3, which travels upon the keel, thereby rendering themovement of the stern-post G easy and accurate. In order to 8o move'thestern-post in or out for the purpose of projecting the supplementalrudder into or out of operation, I employ the rods I,which are connectedto the said supplemental sternpost, said rods working through a beam K,which forms the front wall of the chamber E, and these rods I also passthrough a second beam K', which serves asa guide to hold the said rodsin their proper parallel position. These rods I are connected by across-head go' L, which works upon a screw M, .journaled in suitablebearings mounted in the beams K and K', said screw having a gear Narranged upon its forward end, said gear having a pinion O meshingtherewith, which pinion is operated by the shaft P, driven by anysuitable power. It will thus be seen that by turning the screw ll/I thecross-headv L is caused to travel thereon, and consequently operate thesupplemental stern-post G, which carries the roo supplemental oremergency rudder F. It Will thus be understood that When the main rudderC is carried away the screw is turned to project the supplemental oremergency rudder F rearwardly into the open space E', and thesupplemental emergency rudder thus becomes effective or operative forthe purpose of steering the Vessel. Any suitable means may be employedfor turning the screw for the purpose of moving the rudder in or out.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

l. The combination With the ship having a chamber adjacent to itsstern-post, said chamber having side openings adjacent to the saidstern-post, of a movable rudder and post to which it is connected, andmeans for moving said post and rudder for the purpose specied.

2. The combination with a ship having a chamber adjacent to itsstern-post, of a supplemental rudder located in said chamber and adaptedto move rearwardly to bring the same in operation, and means for movingthe said rudder, as described.

3. The combination with a ship having a main stern-post, of alongitudinal chamber adjacent to the said stern-post, a supplementalstern-post, a supplemental rudder connected to said stern-post, thelongitudinal movable rods connected to the said supplemental stern-post,and means for moving the said rods for the purpose specied.

4. The combination with a ship having a chamber adjacent to itsstern-post, of a supplemental stern-post having rolling supports at itsupper and lower ends, a supplemental rudder pivoted to the supplementalsternpost, the rods connected to said supplemental stern-post, thecross-head connecting the rods, and means for operating the cross-head,whereby the supplemental rudder is moved into or out of operation,substantially as described.
